Structuring your Content


The Introduction heading must be H1: # Introduction

This section is for you to explain the context for this tutorial and why it matters, what we’re going to build and learn in this tutorial.

  • Explain this section like you’re explaining it to 5-year-old (ELI5)
  • Explain everything in 5-6 lines maximum.

For example:

A lot of blockchain projects promise to build a new financial system,but few have thought about mainstream adoption as hard as Celo. With a mobile-first approach where a phone number is all you need to participate in the network, Celo makes cryptocurrency user-friendly and simplifies access to global financial services. Plus, it’s compatible with Ethereum!


  • The Prerequisites heading must be H1: # Prerequisites
  • This section is for you to explain any prior knowledge needed or any existing tutorials that need to be completed first, any tokens that are needed, mention them here.

For example:

  • In this tutorial, we’re going to build a Voting dApp on Celo so before we proceed further make sure to complete the first tutorial “Connect to Celo using hardhat”.
  • Complete the Example Tutorial, first.


The Requirements heading must be H1: # Requirements

OPTIONAL : Embed any video content in this section, if your tutorial has any.

Any technology that needs to be installed prior to starting the tutorial and that the tutorial will not cover (Metamask, node, truffle, etc). Do not list packages that will be installed during the tutorial.

For example:

  • We’ll need Metamask in this tutorial, install it from HERE.
  • Make sure to have NodeJS 12.0.1+ version installed.

Body of the Tutorial

  • Please do not use “Body of the Tutorial” as a heading, use your own heading that is relevant to the material. “Getting started” is acceptable if you can’t think of anything else :wink:
  • Add any text content necessary to guide readers through your tutorial, and remember to proofread your content for spelling and grammar before you submit your tutorial. Grammarly is a good free program that can help you to avoid spelling and grammar problems.

Points to remember:

  • Keep all sub-headings at H2**,** don’t go into H3 or lower**:**
  • Add only necessary comments in code blocks. Do not add # style comments to terminal input code blocks.
  • Add all relevant code blocks:
  • Markdown syntax for code blocks is three backticks at the beginning and the end of the code block. Also make sure that all code blocks have a newline before and after the backticks. For example:


const testVariable = 'some string';



  • ALL code blocks must have a syntax highlighting type, use ```text if you are not sure.
  • ```bash should only be used for code blocks where you need to have # style comments. This must be done carefully because in many situations the # character will render as a markdown heading.
  • Do not use pre-formatted text for emphasis - only use bold or italic text for emphasis.
  • Add Images or code blocks to reflect expected terminal output.
  • Take an error-driven approach when writing your tutorial: Add common errors and steps to troubleshoot the errors, for example:

Not able to connect to the Celo Node, getting an error on executing node connect.js

Let’s check for some common causes:

  • First, make sure you have the .env file saved and it’s in the correct format as given in the tutorial.
  • If you’re getting an error message like UnauthorizedError: {"message": "Invalid authentication credentials"} then make sure to replace the <API_KEY> with your correct API key which you copied from the DataHub Dashboard.
  • Make sure to have the .env file saved in your project root folder.
  • Make sure NODE_URL in the .env file is correct.


  • The Conclusion heading must be H1: # Conclusion
  • This section should summarize what was learned in the tutorial, reinforce key points and also congratulate the learner for completing the tutorial. Use a maximum of 5-6 lines.

Next Steps

The Next Steps heading must be H1: # Next Steps
